Filed in state court in Clark County, Nevada, the proposed class action lawsuit accuses Slide Fire Solutions and other unnamed manufacturers of negligence. It further cites infliction of emotional distress on thousands of witnesses and injured at the Route 91 Harvest music festival.

The lawsuit by three festival attending Nevada residents involves no physical injuries suffered as a result of the shooting or the families of the 58 people killed.

Authorities said the ability to fire hundreds of rounds per minute over a 10-minute period created the high casualty count. Bump stocks allow semiautomatic rifles to operate similar to fully automatic machine guns. Both the product and a modified gun are currently legal in Nevada.

The lawsuit faces very long odds due to legislation by Congress according to Georgia State University law professor Timothy Lytton. The 2005 law shields firearms manufacturers from any liability if their products contribute to the commission of crimes.

The only way the plaintiffs (lawsuit) can survive is if the court accepts the idea that a bump stock accessory is not covered under the U.S. Congress’ components parts definition.”
